Abstract
Tin Sulfide (SnS) semiconductors have captivated attention in recent years as a low-cost photovoltaic material alternative. Tin Sulfide (SnS) was successfully synthesized using a wet-chemical method, yielding a cubic phase that was later annealed at 500 °C to produce an orthorhombic phase. The ac conductivity mechanism and dielectric properties of SnS with cubic and orthorhombic phases were investigated in this paper.Dielectric constant (ε) and ac conductivity (�ac) were measured in frequencies in the rangeof 40 Hz to 20 MHz at room temperature. The dielectric constant and dielectric loss tangent decrease as frequency increases. The increase in frequency-dependent ac conductivity is explained by the correlated barrier hopping (CBH) model. In addition, Nyquist (Cole-Cole) plots of cubic and orthorhombic phases revealed a distinct difference in Nature. Koop's Phenomenological theory helps to explain the variation of dielectric properties. © 2022
